We are looking for my mother-in-laws brother, Charles Weaver. Their father was Harry Baum Weaver from Waynesburg, Pa. We are trying to research her family tree, but since she is no longer with us, we don't know of any other siblings she had. Her brother, Charles, lived in N. Tarrytown back in the early 1950's. We have found documentation on her father, Harry, but would like to talk to other family members, as my husband went into the service at age 17 and never moved back to Pa., so he didn't get the chance to talk to his mother about the family.
